Walk into any gym and you’ll eventually hear it: “Creatine? Mate, that’s why your hairline’s going.” It’s one of the most repeated claims in fitness, and it all traces back to a single study from 2009. Time to look at what it actually said.
Where the panic started
The study followed college rugby players taking creatine for three weeks. Researchers measured a rise in DHT, the hormone that drives male pattern hair loss in genetically susceptible men. The internet did the rest.
Here’s what usually gets left out. The study measured hormone levels, not hair loss. Not a single participant was checked for shedding or thinning. DHT levels rose but stayed within the normal range. The sample was about 20 people. And in the fifteen-plus years since, no study has replicated the finding, despite creatine being one of the most researched supplements on the planet.
So what do the gym bros get right?
One thing, partially: DHT genuinely is the main driver of male pattern baldness. If your follicles are genetically sensitive to it, more DHT is not what you want. So the concern isn’t invented from nothing. It’s just built on remarkably thin evidence.
What they get wrong is the conclusion. If creatine meaningfully accelerated hair loss, we’d expect to see it in the data by now, across millions of users and hundreds of studies. We don’t. Reviews of the evidence consistently land in the same place: no demonstrated link between creatine and hair loss.
What actually matters for your hairline
Genetics. If male pattern hair loss runs in your family, that is the factor doing the heavy lifting, not your supplement shelf. Training hard, eating enough protein and sleeping properly all support healthy hair far more than avoiding creatine will protect it.
If you’re genetically prone and want to hedge your bets, there are more direct moves than dropping a supplement that works: a daily routine that supports the scalp (a caffeine shampoo and serum are an easy base), and for those thinking specifically about DHT, saw palmetto, a plant extract studied for its ability to interfere with the enzyme that converts testosterone into DHT. We offer it as a simple daily tablet for exactly this crowd.
The verdict
Keep the creatine. Watch your hairline like you’d watch anything else that runs in the family, and if you notice early thinning, act early. That’s the one habit that reliably pays off.
